How to choose the combustion mode of muffle furnace?

When you buy muffle furnace, you will have a variety of combustion methods for you to choose. Today, we will briefly talk about how to choose the combustion mode of muffle furnace?

1. In order to achieve the economic operation index, it is necessary to solve the problem of complete fuel combustion. How to choose?

2. High enough furnace temperature is the primary condition for fuel combustion. The low temperature at which the fuel begins to react violently is called the ignition temperature. The heat required to heat the fuel above the ignition temperature is called a heat source. The heat source of fuel ignition in combustion chamber usually comes from heat radiation of flame and furnace wall and contact with high temperature flue gas. The furnace temperature of muffle furnace, which consists of heat source, must be kept above the ignition temperature of fuel, that is to say, the furnace temperature must be high enough for continuous combustion of fuel. Otherwise, the fuel will be difficult to ignite, unable to burn or even cut off.

3. Proper amount of air. Fuel must be fully contacted and mixed with enough gas in air when burning. When the furnace temperature is high enough, the combustion reaction speed is very fast, and the oxygen in the air will be consumed quickly. Therefore, sufficient air must be supplied. However, in actual operation, the air sent into the furnace is surplus, but the excess air quantity cannot be too much, so it should be appropriate to avoid reducing the furnace temperature.
